Alternator alternatives??

[seenastyle]

On this and other forums, I've only seen very light treatment of this topic so I figure a direct post would be helpful: My alternator's gone bad, and through the usual vendors, the Aston-branded one is silly expensive. But I *think* this alternator model's used in tons of other cars. Has anyone installed the equivalent?

I think it’s a Denso SC1 150 Amps at least for the V8V, which appears in the Aston Workshop Manual (page 14-2-1). Aston OEM part# is 6G43-14-10051, but I’m also seeing it as 4W4T-10300-AA and a bunch of other numbers everywhere. I even see it on Amazon with Prime delivery!! www.amazon.com/gp/product/B091J4BD1T and www.amazon.com/gp/product/B007Y85FJM . Heads up that the Amazon items are remanufactured and don't have great reviews, so vendor recommendations of the new part would be appreciated.

I'm crossing my fingers for answers like "I bought this model from this website for this much and it totally fit physically / electrically".

Ps, another cost-conscious option is to have the alternator rebuilt, but kind of curious where this road leads, pardon the pun,

Have you been able to remove your old one and have a look to see if there are any part numbers referring to a Ford or Jag part?

I've got a alternative parts topic sticky on this forum, don't think there is anything about an alternative alternator in there, so if you do find an equivalent part please let us know and post it in the alternative sticky, thanks.

Good luck, and hopefully someone here might have already done this.

I’ve had a couple of alternators rebuilt. Not expensive (£80 shipped back to me). All cleaned up, renewed where needed and working fine.

Admittedly not an Aston one, but they’re all pretty much the same principle. I’d definitely do it for the Vantage if it ever goes bad.

The Alternatorman is who I’ve used before, down Southampton way.

I can tell you it's a mission to get it out - no access space and some very inaccessible fixings.

I think wherever you go it will be a reconditioned one anyway, thats why they are always an exchange item, even from a main dealer.

Thanks all. Circling back here to report what worked: My indy mech and I ordered a rebuilt item of that part number (4W4T-10300-AA), which apparently goes into at least the 2004 Ford Lincoln Thunderbird LS. Lo and behold, it worked! And at $189 USD, when the dealer quotes almost 10x that, I'm not complaining. My indy mech threw in a new AGM-technology battery while at it. If you haven't watched Redpants' (user @telum01 on the forum) videos about AGM batteries, I highly recommend. He's got no less than 3 videos on the battery topic.
